Note that the NOMADS OpenDAP urls aggregate all of the nowcast and forecast times into
two urls (forecast, nowcast) for each type of file (2ds diag or 2ds prog surface files, 3ztio, 3zsio,
3zuio, and 3zvio full-volume data).

For analyzing the
model data in MATLAB® we recommend the
NCTOOLBOX for MATLAB. NCTOOLBOX can read NetCDF, OPeNDAP, HDF5, GRIB,
GRIB2, HDF4 and many (15+) other file formats. The complete list of formats
is
available here.

Notes on processing Global RTOFS data

The interpolated and native global horizontal grids are very large
(3298x4500 native, 14.8 million grid points), (2160x4320 interpolated, 9.3
million grid points). Loading and mapping a single layer of the full global
grid takes a considerable amount of memory.
